After using J B weld on the back glass channel I painted all the way around the channel with epoxy primer with a small paint brush. I did that because it looks like water can seep between the glass an the trim an stand in the channel, being J B weld is non-hygroscopic it seem to be the best protection from more damage. I did the same thing on the t-top channels as they were pitted also. Just wanted to be sure of having a good seal.

Good point well made sir! I agree too, JB Weld is a strong bonding and sealing product. I have used it for pin holes and small pitted ares that after properly cleaning the spots lasted forever.
